Bootiful Spring Boot 3
summary
Spring Boot 3 moves to a Java 17 baseline and Spring Framework 6 with Jakarta EE package names, adds Micrometer tracing (unified metrics+tracing), RFC7807 Problem Details error responses, declarative HTTP/RSocket clients and GraphQL with batch resolvers, and first-class AOT GraalVM native-image support that produces tiny runtimes (~100 MB RSS) but incurs slow native compiles (minutes). Actuator endpoints, buildpacks and boot build-image work for containers; demos compile, run and return expected results.
